Could your smartphone prevent a car from hitting you? General Motors and other researchers think that’s a possibility【C1】________an emerging wireless standard works its way into the latest smartphones and new cars.
First seen in 2010, Wi-Fi Direct【C2】________ultrafast device-to-device connections over the same radio waves that smartphones, computers and other electronics currently use to connect to routers and home networks. The【C3】________here is that unlike your application-enabled television, Wi-Fi Direct doesn’t【C4】________the Internet. Rather, it’s【C5】________connect local devices directly to each other【C6】________as little as a second, and unlike Bluetooth, the connection doesn’t require special pass keys and works at more than double the【C7】________, at about 656 feet apart. GM says future cars could【C8】________pedestrians carrying Wi-Fi Direct smartphones, gather their【C9】________locations and warn the driver through existing active safety systems such as forward collision【C10】________and auto-braking.
Wi-Fi Direct is one part of GM’s research on vehicle-to-vehicle and vehicle-to-infrastructure【C11】________in which both cars and roadways become【C12】________aware and adaptive to real-time information. More and more automakers, such as BMW and Hyundai, use a subscription-based 3G cell network to connect a car’s information & entertainment system to the Web for things such as【C13】________searches. A few automakers, such as Ford and Audi,【C14】________wireless hotspots that allow full【C15】________to the Internet from any mobile device. By 2015, Ford said it【C16】________80 percent of the vehicles it sells in North America to have a Wi-Fi connection.
Wi-Fi Direct currently allows file【C17】________between two electronic devices【C18】________having to pair them. If the technology becomes popular and【C19】________it could pull the market away from Bluetooth, the short-range wireless standard for in-car telephone calls and portable audio. With Bluetooth, there isn’t one【C20】________way to connect a device—and many times, as we’ve often found, it still doesn’t work. According to data from the National Highway Traffic Safety Administration, nearly 4,900 pedestrians and cyclists were killed by cars last year, for which data were available.
【C18】
选项
A、until
B、upon
C、without
D、through
答案
C
解析
第二段提到Wi-Fi Direct与蓝牙技术的区别之一是它不用特别指令(special pass keys)即可实现连接。既然Wi-Fi Direct不需要特别的指令。也就是不需要having to pair them (配对),因此空格处介词应含有否定意义,选C项without。A项until“直到”代入后强调的是“传输文件”持续时间,不侧重Wi-Fi Direct的工作原理,所表达的语义也不符合语境要求。B项upon有“一……就”的意思,它和D项through“通过”代入后所表示的意思与文章的语义提示相反。
